1. 1

   Check the current software version of the CSM to ensure there are no software mismatches (baseline software version for the AFS Connect Magnum CSM is 1.0.0.0).

2. 2

   Test the CAN bus wiring harness between the CSM and the vehicle controller for opens, shorts to ground, or damaged pins in the connectors.

3. 3

   Verify that the Cab Suspension Module is receiving proper voltage and has a clean ground connection.

1. 1

   Repair Wiring

   If diagnostic testing reveals a break or short in the CAN wiring harness, repair or replace the affected harness section.

2. 2

   Reflash/Update Module

   If the wiring is intact, the CSM may require a software reflash. Note: A failure while flashing the module can render it inoperable and unable to communicate on the network.

3. 3

   Replace Module

   If the CSM has internal hardware damage and cannot establish communication with the vehicle controller despite good wiring and power, the module must be replaced.
